You can't be released from liability for doing something stupid and harmful just by warning people that you're about to do something stupid and harmful.

Okay, fine. They "gave customers a 10 day ultimatum, at which time they said they would forfeit the Bitcoin Cash because it's unsupported."
You can't do that. It doesn't matter if it's technically complicated to implement a disbursement system, it doesn't matter if anyone can decide to fork a cryptocurrency. A customer's asset cannot be denied to them (potentially, and as originally stated, into perpetuity) with 10 days notice. This is not how any exchange operates, and the fact that Coinbase is attempting to do it is beyond the pale.
